ADJUSTABLE CHUTE coivs'rniierioit b all Iwhom t may concern:

Be it known that I, Cani. D. Hernia, a` citizen of the United States, residingat 'Council Bluffs, in the county oi" Pottawattainie and State of iowa, have invented certain new and useful Improvements in Adjustable Chute Constructions, ot' which the following'is a specification.

The present invention relates to improvement inv what I term labor'saving devices, more particularly characterized as aii`adjustable chute designed especially :tor use in loading` and unloading operations. The inventionI consists primarily in a frame, preferably extensible or adjustable7 and means tor attaching and holdingthe frame. in operative position.

An object is 0to provide special attaching means readilyfapplicable to a support for sustaining the chute not only iii operative position but also in an inoperative position, which latter position is assumed upon a incre release of one of the ends of the chute.

A further object is to provide a chute of this type that may be easily collapsed linto a compact t'orn'i tor storage or shipment.

These and such other objects as may lier inafter appear are attained by the novel construction, combination and arrangement of parts to be hereinafterspecitieally described and claimed. Reference will now be had to the accompanying drawings forming a pai-t o't this speciticatioiijwherein:

Figure l is a side .elevation et a device constructed in accordance with my invention and showing the. saine in 'operative position in tull lines. the supports to which it is attached being in section, and further showing in dotted lines the inoperative position ol' the device;

Fig, 2 is atop plan view of the iiivenf tion;

Fie". 5 is a sectional viewv on the line-5 ot Fig. 1; andv l Fig, G is a detail View ot the spring' used in connection with this device. f

Throughout the following detail description and on the several iigures of the drawings, similar .parts are referred to by litre reference charactersu Y Specification of Letters Patent.

Application filed May .1.1, 1?@8. i Serial No. 233,923.

Patented June t?, iiiliila The device which constitutes the subject matter ot this application consists primarily ot a pair ot side members each or' which is composed of a lower section lv and a telescopic upper section 2 designed to beheld in cooperativi-i relation by means ot a set screw These side members are preterably cylindrical inform and are connected at their upper ends by a suitable rod having removable nuts 5 at the ends. The bottoni or body ci the chute is termed by a canvas or similar i'i'abric apron 6 which at each side is liemmed so as toi'eceive in the liemined portion the respective side members of the trame. The canvas is'piovidcd with an elon gated openingl as indicated at 7 adjacent to the set screw 3 at each side so as to allow tor adjustment of the parts whereby the sides are disposed in proper` relation to each other. ln other words, it is to be iinderstood that these side members may be adj usted toward or from each other so as to affect the width of the chute or they may be adjusted with respectto their longitudinal dimension, in which `latter adjustment the canvas is sutticientiy flexible to accommodate the adjustment. rThat is to say, if the adjustn'ieut. of the side members in length is shorter than the normal full length ot` the canvas the canvas will lie in folds as will readily be understood by those skilled in this art. i

At the upper end the chute is provided with the overlapping" tlap 8 having' a series oit l openings or eyelets 9 therethrough `by means ot which this upper end o't the. chute is adapted to be attac-lied to a support l0 which 'may be a bin. crib7 car` or the like7 while at the lower end a similar flap" 1i is provided to over iangr intotlie body of the wagon or other vehicle indicated at 1:2.

rEhe lower end of the chiite isffheld in lined.

tit

relation to the wagon 12 by mea/ns et suitable clamping means now to be described. Each ot the traint` members has pivotal connection with a clamping-device 13 of substantially lil-shaped configuration and each legl of this clampingdevice carries an eccentric cam 14. At one side each oi" the cams 14 has a serrated element 15 with which a pivoted dog" i6 carried by the particular leg' ot' the U- shaped member 13 engages. 1When the ll Ishaped men'iber has been inserted over the side of the Wagon 12 the cani levers or niembeis 14 yare pressed downwardly and thereby forced against`said side 12, being held in tight clamping relation by the .pawl or dog 16 above referred to. Surroundlng the pivot 17 between the clamping device and the side A a nail or similar object 19..th'rough yone of i the eyelets 9 and when the flap 8 is released from the nail the chute will move into a vertical position shown in dotted lines in Fig. l.

It Will lbe obvious from the foregoing description that a simple and relatively cheap device is providedwhich is particularly useful when it isdesired to shovel grain or the like from arw'agon into a oar, in which operation the grain which falls from the shovel in the process of throwing will pass down the chute back into the body. Obviously the contents of the ear may be similarly introduced into the Wagon body by shoveling the same into the chute in the ordinary manner and I .do not wish to be restricted to any special use of the device in question.

It might further be added that when it is desired to fold the chute it is only necessary to move the side men'ibers together' after removal of the rod 4 and to shift lthe upper sections of the frame members into their telescoped position.

Having thus described my invention7 what, I claim as new is:

Supporting means for chutes of the class described comprising spaced 'gripping devices pivotally connected to the chute at one end, each having means for clamping the devices to a suitable support, and springs be.

tween the devices and the chute tending to throw the chute into an elevated position when lthe other end thereof is free to move.

ln testimony whereof I affix my signature.
